The emo rapper (real name Gustav Åhr) passed away earlier this month (November 15) from a suspected drug overdose, although a definitive cause of death will not be determined until full toxicology results are published. He was 21.

TMZ now reports that Tucson police are investigating whether fentanyl – the drug also thought to have played a role in Prince’s death – may have factored into Peep’s suspected overdose. Police are said to have received “multiple tips” that Peep was in possession of “incredibly toxic drugs laced with the potent opioid”. The Tucson Police Department have not yet confirmed the reports.

It has also been reported that Peep was found dead on his tour bus with drug paraphernalia, Xanax, marijuana and an unknown tan powder also found in the vehicle.
